Article Synopsis
- The Sundarbans, a UNESCO heritage site, is one of the largest mangrove forests and has been under-studied for its endophytic fungi, leading to the isolation of fourteen fungal strains from local mangrove plants.
- Five of the strains were identified through microscopic observation, and their extracts demonstrated significant antibacterial activity against several bacterial strains, with minimum inhibitory concentrations (MICs) ranging from 5 to 0.078 mg/mL.
- The study also successfully isolated three compounds (fumigaclavine C, azaspirofuran B, and fraxetin) from one highly active endophyte, with fraxetin being reported for the first time from this source, indicating potential for discovering new antimicrobial
(Mart.) Griseb., commonly known as "Alligator weed" in English, and "Malancha" in Bengali, is a leafy vegetable from the family Amaranthaceae A.

In the backdrop of the recent revival of interest in developing plant-based insecticides, this study was carried out to investigate the pesticidal activity of Sundarban mangrove plants. A total of nine different plant parts from five plants, namely, , , , and , were extracted with methanol and tested for insecticidal activity against two common stored product pests and using direct contact feeding deterrent wafer disc method.

(Rutaceae), a perennial herb with wild and cultivated habitats, is well known for its traditional uses as an anti-inflammatory, analgesic, antipyretic agent, and in the treatment of rheumatism, nerve diseases, neuralgia, dropsy, convulsions and mental disorders. The antimicrobial activities of the crude extracts from the fruits, leaves, stem and roots of were initially evaluated against two Gram-positive and two Gram-negative bacterial strains and a strain of the fungus .

- Calanolides are a group of compounds known for their anti-HIV-1 activity, particularly Calanolide A, which inhibits reverse transcriptase and is classified as a non-nucleoside reverse transcriptase inhibitor (NNRTI).
- There are at least 15 naturally occurring calanolides, mainly from specific plant genera, which also show potential in treating cancer, antimicrobial, and antiparasitic conditions.
- The review article provides an in-depth overview of calanolides, covering their chemistry, natural occurrence, how they are made, their pharmacological and toxicological effects, mechanisms of action, and related patents.
Objectives: Cicca acida L., is reported with traditional and pharmacological uses, and a good number of pure compounds have been isolated from its different parts. But published information is sporadic and fragmentary in nature.

Valuable information collected from these communities in the present investigation is important in maintaining their indigenous knowledge of folklore medicine.
Methods: Systematic and extensive field surveys were conducted during 2011-2013 among the ethnic inhabitants of Unokati district, Tripura, India covering all the seasons to collect information on their traditional herbal medication system for treatment of diabetes.
Ethnopharmacological Relevance: Ricinus communis L. (Rc), of Euphorbiaceae family is a widespread plant in tropical regions and it is used in traditional medicines as an antifertility agent in India and different parts of the world.
Aim Of The Study: The aim of the present study is to revalidate the ethnobotanical knowledge by evaluating the activity of only crude stem bark extracts of Rc.
